Paper Abstract

When heated the living tissue exhibits random nonuniformities in the temperature that are due to the discreetness of vessel arrangement. Because of strong temperature dependence of the thermal coagulation rate these nonuniformities should substantially affect the necrosis growth induced by local heating. In the present work we study their effect on the form of a necrosis domain when its growth is limited by heat diffusion into the surrounding tissue. In particular, we analyze the mean amplitude and the correlation length of the interface perturbations depending on the main characteristics of the random temperature nonuniformities.
